>             Project: Spark
>          Issue Type: Improvement
>          Components: Java API, PySpark
>    Affects Versions: 3.0.1
>            Reporter: Malthe Borch
>            Priority: Minor

> From the [SQL functions|https://spark.apache.org/docs/latest/api/java/org/apache/spark/sql/functions.html] documentation:
> {quote}Commonly used functions available for DataFrame operations. Using functions defined here provides a little bit more compile-time safety to make sure the function exists. {quote}
> Functions such as "inline_outer" are actually commonly used, but are not currently included in the API, meaning that we lose compile-time safety for those invocations. We should implement the required function definitions for the remaining built-in functions when applicable.
